OMAI-IUAK. 21 



reritly raised central line smooth, the outer borders of the depressions nearly 

 so, the punctation and vestiture like those of the head. Elytra slightly 

 broader than thorax, oblong, parallel-sided, truncate behind ; their punc- 

 tation well marked and almost quite seiiate, with somewhat irregular 

 feebly elevated interstices, producing a substriate appearance. Hind-hody 

 of about the same length and breadth as the elytra, slightly transversely 

 convex ; the basal 4 segments equal, finely sculptured, with broad flattened 

 margi)is ; 5th nearly smooth, rather longer than 4th ; the pubescence 

 greyish and distinct. 



This most nearly resembles /. niorosus ; it is smaller and even darker, 

 but with paler legs. The median mark oii the 2nd dorsal segment is less 

 distinct ; in /. morosus it resembles a minute horse-shoe. 



Length, 1^ lines ; breadth, quite | line. 



Waitakerei Range. March, 1909. My specimen was caught under the 

 bark of a decaying nikau log ; others effected their escape. 



Group P.SELAPHfDAE. 



3048. Yidamus spinipes sp. iidv. Gen., Rafiray, " Genera oi Pselfahidae" 



Xitid, fusco-rufous ; the legs, antennae, and palpi paler ; the pubescence 

 yellowish, fine yet distinct. 



Head large, as broad as thorax, subquadrate, but narrowed in front of the 

 small but prominent eyes ; it is broadly bisulcate ; the antennal tubercles, 

 though distant, appear nevertheless to form a broad continuous frontal 

 margin ; the slender hairs are disposed transversely. Thorax dilated late- 

 rally before the middle, much narrowed in front, more gradually towards 

 the base ; at each side near the base there is a deep fovea, and an angular 

 one between them, united by a curvate impression or groove. Elytra 

 oblong, rather broader than thorax, a little narrowed towards the base ; 

 sutural striae deep and broad, the shoulders appear elevated owing to the 

 presence of an elongated fovea alongside each, there is a minute basal fovea 

 near each side of the suture, the dorsal striae are obsolete, their surface 

 with shallow indistinct punctures. Hind-hody nearly as large as the elytra, 

 finely punctate, 2nd and 3rd segments equal, 4th and 5th deflexed. 



Legs elongate ; intermediate tibiae on the inner side, between the middle 

 and extremity, with a conspicuous spiniform process ; the posterior simple. 



Antennae about as long as head and thorax ; basal joint stout ; 2nd 

 nearly as long as the exposed portion of 1st, but not quite as thick ; 3rd 

 slightly longer than broad ; 4-8 moniliform ; 4th and 5th rather larger than 

 the others ; 9th and 10th evidently broader, and narrowed towards the 

 extremity ; 11th large, subobconical. 



This species can be recognised by the armature of the middle tibiae.

Broken River. My specimen was found by Mr. J. H. Lewis. 



3049. Sagolonus impressus sp. nov. Gen., Raff., "Genera of Pselnphidae.'' 

 Elongate, slightly convex, shining, rufous, elytra rather paler, legs obscure 



rufo-testaceous, tarsi and palpi flavescent, antennae testaceous ; pubescence 

 yellow, fine yet distinct. 



Head large, much curvedly narrowed behind the prominent eyes, and 

 widest in line with them ; antennal tubercles evidently separated, inter- 

 ocular foveae moderate, apparently prolonged forwards and convergent near 

 the tubercles, with some fine punctures near the sides, smooth in front. 

 Thorax longer than broad, widest just before the middle, considerably and
